When Can a Second Home Be Considered a Primary Residence? - Eatons

It’s becoming more common in the UK to end up owning more than one property through marriage, inheritance or simply choosing to buy a holiday home. What gets more complicated is understanding which property counts as your main residence and how that has real tax implications, particularly when it comes to selling.
A second home can legally be considered your main or primary residence for tax purposes, such as Private Residence Relief from Capital Gains Tax, if you formally nominate it within two years of acquiring the combination of properties, or if the day to day facts of your lifestyle show it is genuinely your primary base of living.
Owning two or more properties brings a number of legal and tax considerations, and Capital Gains Tax is usually the biggest of these. Only one property can benefit from the main residence exemption at any one time, so if you later sell a property that was not treated as your main home, some or all of the gain could be chargeable.
There can also be other implications depending on how the second property was acquired and used, such as an additional rate of Stamp Duty Land Tax on the purchase of a second residential property, and Inheritance Tax considerations if a property forms part of an estate. Because CGT on property can get very complex, particularly where a nomination has not been made or the facts are not clear cut, it is always sensible to get professional tax advice alongside legal advice before selling or transferring a second property.
Capital Gains Tax (CGT) is a tax on the profit you make when you sell or otherwise dispose of an asset that has increased in value. It’s the gain that is taxed, not the total amount you receive for the property.
Property is one of the assets most commonly affected by CGT. However, your only or main residence is normally protected from this tax through Private Residence Relief, which exempts some or all of the gain when you sell your main home. The complication arises once you own more than one property, since only one of them can be your main residence for CGT purposes at any given time.
Yes- if you own two or more properties that you use as homes, you are able to nominate which one should be treated as your main residence for CGT purposes.
This nomination must be made in writing to HMRC within two years of the date you first have those residences. If your combination of properties changes again later, for example if you buy or sell another property, a new two year window begins from that point. You can also change your nomination at any time, and the new nomination will take effect from the date you notify HMRC, rather than being backdated.
It’s important to note that simply nominating a property is not enough on its own. HMRC and the courts have made it clear that a property must be occupied at least some of the time to count as a residence. This means you need to actually live in the property as a home at some point to be able to nominate it as your primary residence.
There is one further point worth knowing about timing. The final nine months of ownership of a property that has been your main residence at some point are always treated as qualifying for relief, regardless of whether you are living there or not during that period. This gives some breathing room to sell without losing the full exemption.
If you do not make a nomination within the two year window, or your nomination is not valid, HMRC will decide which of your properties is your main residence based on a combination of facts, rather than a straightforward count of how long you reside in each property. This can include factors such as:
No single factor is decisive on its own. Instead, HMRC and the tribunals look at the overall picture to work out where your real home is, so it is the pattern of ties across several of these factors that tends to matter most.
A few other points are worth bearing in mind when it comes to second homes and primary residence status.
If you’re married or in a civil partnership and you are not separated, you and your spouse or civil partner can only have one main residence between you, even if you each owned a separate property before marrying. Where this applies, the two year window for making a joint nomination begins from the date of the marriage or civil partnership.
If you separate, you and your spouse or civil partner may each have your own main residence going forward, and each of you may be entitled to relief on the property you live in.
Inheriting a second property is another common trigger for this issue, since the person receiving the property may already own their own home. HMRC are more likely to scrutinise a main residence nomination where a property is sold reasonably soon after being acquired and there is a significant gain, so keeping evidence of genuine occupation matters if you intend to rely on it.
Finally, if you let out all or part of a property that has also been your home at some point, this can affect the amount of relief available and may bring other tax rules into play. Given how many personal circumstances can affect the outcome, from marriage and separation to inheritance and letting, it’s worth taking specific advice on your own situation rather than relying on general rules of thumb.
Deciding which of your properties should be treated as your main residence often comes hand in hand with a wider legal matter, whether that is buying a holiday home or investment property, inheriting a property through probate or a will, or working out what happens to jointly owned properties during a divorce or separation.
